APPARATUS FOR ASSEMBLING KNIVES.

Application filed September 21, 1926.

My invention relates to improvements in apparatus for assembling knives, such as pocket knives. More particularly my invention relates to apparatuscomprising a a pair of clamping members adapted to have the rivets of the knives fixed between the same, and means for pressing the parts of the knife put on the said rivets. The object of'the improvements is to provide an apparatus of this kind which is simple in construction and reliable in operation, and with this object in view my invention consists in constructing the co-opcrating clamping members each of an integral plate, the cooperating end faces of the said plates being formed with corresponding portions adapted to hold the rivets in the proper relative positions.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawings, in which the same letters of reference have been used in all the views to indicate corresponding parts. In said drawings,

Fig. l is a top plan view showing the 00- operating clamping plates,

Fig. 2 is a top plan view showingthe apparatus with parts of the knife placedthereon,

Fig. 3 is an elevation of the apparatus looking from the bottom side of' Fig. 2,

and

Fig. l is a sectional elevation taken on the line 4-4 of Fig. 41;. 7

As shown in the drawings, the clamping apparatus consists of a pair, of clamping jaws 1 and 2 each consisting of an integral plate, said jaws being provided at their engaging end faces with three semi-circular recesses 3 providing seats for thethreerivets 20 of the knives. The seat for the median rivet is displaced withrelation to the seats for the outer rivets, according to the usual position of the rivets of pocket knives. The plate or jaw is fixed to the frame 4, while the plate or jaw 1 is movable on the said frame towards and away from the plate 2.

The movable plate 1 is formed at its rear end with a downwardly directed heel16 acted upon by a spring 17 tending to hold the plate in engagement with an elongated cam 18 the shaft of which carries a hand lever '21 for moving the plate 1 towards the plate 2 in opposition to the spring 17 for clamping the pins or rivets 20. or limiting the rock ing movement of the said hand lever an arm Serial No. 136,872.

22 is provided on the hub of the said lever, which projects downwardly between a pair of stop members 23 adjustably secured to.

and clamping them between the plates 1 and 2, and while these jawsare in their closed position the lower plate a, the lower shell I), the blade 0, and its spring 41, the upper shell 5, and finally the upper plate 6 are placed on the rivet-s by hand, the said rivets passing through the bores of the said parts, the lever 31 during these steps being in the raised position.

After the parts of the knife have been thus assembled, they are pressed together by means of a plate 32 carried by a hand lever 31 and formed with recesses 33 for the upper ends of the rivets. By rocking the lever 31 and the plate 32 downwardly, the parts of the knife are pressed together, whereupon the lever 31 and plate 32 are rocked'upwardly and away from the knife. The clamping jaw 1' is moved while the plate 32 is in its downward position. The hub of the hand lever 31 is formed with a lug 34 which in the elevated position of the said lever engages a stop holding the same in position while the parts of the knife are being assembled or the assembled knife is removed from the apparatus. y

In. order to put the spring 41 of the knife under tension after assembling the parts, and to place the same at the rear of the heel of theblade when compressing the parts of the knife, a lever 24 is provided, an arm 26 of which is adapted to pass between the shells b and cl.

I claim 1. 'An apparatus for assembling knives,

comprising a pair of integral clamping plates adapted to hold the rivets of the knife between the same, means for throwing the plates into clamping engagement with each other and means for pressing the assembled parts of the knife together.

2. An apparatus for assembling knives, comprising a pair of integral clamping plates formed with corresponding recesses adapted to hold the rivets of the knife between the same, means for throwing the plates into clamping engagement with each other, and means for pressing the assembled parts of the knife together.

3. An apparatus for assembling knives, lever. provided with an arm in position for comprising a pair of integral clamping being passed between the shells of the knife plates adapted to hold the rivets of the being assembled and into engagement with l knife between the same, means for throwing the spring of the knife. 5 the plates into clamping engagement with In testimony whereof I hereunto affix'my each other, means for pressing the assembled signature. 7 parts of the knife together, and a rocking ERNST GERLING.
